摘要： An ophthalmic technician is present with a patient in an exam room to operate eye examination equipment and transmit patient information to remote location. At that remote location, a skilled technician is present to provide the necessary optical care, and may operate the phoropter from the remote location. Using video and/or teleconferencing equipment and a phoropter located in the patient examination room along with management software, the system works to determine the final optical prescription for the patient. That information, coupled with findings from other devices which are integrated with the management software, and that the patient uses locally, are reviewed by a remote-based optometrist or ophthalmologist.

摘要： The present invention provides a system and a method for measuring ocular motility of a patient. The system comprises a display unit capable of presenting at least one target; a blocking unit configured and operable to selectively block/unblock at least one target in a field of view of at least one eye of the patient; a camera unit comprising at least one imaging element configured and operable to generate at least two image data indicative of at least one eye condition; and a processing unit connected to the blocking unit, to the display unit and to the camera unit, the processing unit being configured for performing the following steps: (a) displaying at least one target, for at least one eye (b) receiving image data indicative of at least one eye's condition from the camera unit, (c) controlling the blocking unit to block/unblock at least one target in the field of view of at least one eye of the patient, (d) detecting a change in at least one eye's condition, (e) displacing the target for at least one eye; and repeating steps (a)-(e) until no change in the eye's condition is measured to thereby determine at least one ocular motility parameter.

摘要： A method of determining a refractive power value characterising an ophthalmic lens for correction of an individual's eye ametropia includes: obtaining first data representative of a refraction value and second data representative of a position of the individual's head with respect to a refraction apparatus when the refraction value was determined; determining the refractive power value as a function of the first data and of a relative position, derived the second data, of the refraction apparatus with respect to a centre of rotation of the eye when the refraction value was determined. A corresponding electronic device is also proposed.

摘要： The various embodiments herein provide a system and method for direct and consensual pupillary light reflex stimulation without cross-contamination of contralateral eye. The embodiments also provides a portable and easy-to-use system and method for eye stimulation of pupillary response assessment for medical evaluation. The system is a portable and head-mounted goggles system is provided for eye stimulation of pupillary response assessment. The head-mounted goggles system comprises a visor, a pair of LEDs, a pair of well-arrangement and two cameras. The well-arrangements are designed in such a way that the LEDs provide a narrow light cone only to the eye under observation and prevents the contralateral eye from being stimulated. The cameras are independent of each other and are configured to capture images and transmit the images to a remote computing device through wired and/or wireless means.

摘要： A vision protection method is provided to ensure a viewer to rest his/her eyes after viewing on an electronic device for a certain period, wherein the eyesight protection method includes the steps of detecting at least one of eye activities of the viewer and working parameter of the electronic device in a working mode of the electronic device during the viewer is working on a current work displaying by the electronic device; switching the working mode of the electronic device to a resting mode when an abnormal eye activity of the viewer is detected; and switching the electronic device from the resting mode back to the working mode to resume the display of the current work of the electronic device. Therefore, the viewer is enforced to rest his/her eyes after every certain period.
